Recommended Java library for creating a video programmatically [closed]

Question

Can anyone recommend a Java library that would allow me to create a video programmatically? Specifically, it would do the following:

• take a series of BufferedImages as the frames
• allow a background WAV/MP3 to be added
• allow 'incidental' WAV/MP3s to be added at arbitrarily, programmatically specified points
• output the video in a common format (MPEG etc)

Can anybody recommend anything? For the picture/sound mixing, I'd even live with something that took a series of frames, and for each frame I had to supply the raw bytes of uncompressed sound data associated with that frame.

P.S. It doesn't even have to be a "third party library" as such if the Java Media Framework has the calls to achieve the above, but from my sketchy memory I have a feeling it doesn't.

Answer 1

I've used the code mentioned below to successfully perform items 1, 2, and 4 on your requirements list in pure Java. It's worth a look and you could probably figure out how to include #3.

Answer 2

I found a tool called ffmpeg which can convert multimedia files form one format to another. There is a filter called libavfilter in ffmpeg which is the substitute for vhook which allows the video/audio to be modified or examined between the decoder and the encoder. I think it should be possible to input raw frames and generate video. I researched on any java implementation of ffmpeg and found the page titled "Getting Started with FFMPEG-JAVA" which is a JAVA wrapper around FFMPEG using JNA.
